APPARATUS FOR CONSUMPTION OF SEWER-GAS.

SPECIFICATION forming part of Letters Patent No. 481,108, dated August16, 1892.

Application filed March 9, 1892. Serial No. 424,315. (No model.)

To a/ZZ whom t may concern.-

Be it known that I, JACOB ECKHARDT, of the city of St. Louis,in theState of Missouri, have invented a certain new and useful Improvement inApparatus for Consumption of Sewer-Gas, of which the following is afull, clear, and exact description, reference being had to theaccompanying drawings, forming part of this specification.

This apparatus isintended specially to lead off the gas fromprivy-vaults and to make it available for illuminating purposes. Thenovel features will be set forth in the claims.

Figure I is a vertical section of the apparatus. Fig. II is a horizontalsection taken at II II, Fig. I. Fig. III is a detail front view of thelower portion of the heating-chamber. Fig. IV is a vertical sectiontaken at IV IV, Fig. III. A

1 is the privy-vault.-

2 is a hood or cover fitting tightly at its margin to the Walls of thevault.

3 are the receiving-tubes of the vault, said tubes passing through thehood or cover 2 with a tight joint and descending some distance belowthe hood, so the volatile gas shall not escape from the hood into thetubes. In Figs. I and II these tubes are shown passing through the combof the hood. They may, however, pass through other parts, as indicatedby dotted lines in Fig. Il.

4. is a discharge-tube leading to a sewer 5.

6 is a pipe leading from the apex 7 of the hood or cover 2 to the bottomof a receiver 8, from Whose top apipe 9 leads to a coil 10 in aheating-chamber 11. Any vapor mixed'with the gas :may condense in thereceiver S and flow back through the pipe 6 into the vault and find exitinto the sewer. The coil 10 discharges througha pipe 12, extending fromits apex into the bottom of the storing-tank 13.

14C is a pipe extending from the top of the tank t0 the burners of lampsupon the alley or street or located in some other place.

l5 is a pipe leading from the top of the tank to the bottom of theheating chamber 11. The pipe 15 enters the chamber 11 and has at itsupturned end a burner 16, Whose flame heats the chamber. Over the burneris a hood 17, of metal gauze or perforate metal, adapted to diffuse theheat from the burner. The orifices of the hood 17 may be so small as toprevent the passage of flame, if preferred. f

18 is a door giving access to the burner 16. Oriflces 19 may be made inthe door 18 or other part of the heating-chamber for air to supply theburner and for escape of the products of combustion.

The operation of the apparatus is as follows: Volatile gas forming inthe vault will escape through the pipe 6 to the receivingchamber, fromwhence the condensed vapors flow back in liquid form to the vault. Thegas becomes heated in flowing through the coil and is discharged intothe tank 13. From the tank 13 the gas escapes through the pipe 14. tostreet or other lamps and through the pipe 15 to the burner 16, by whichthe gas is heated and the current induced from the vault to the tank 13.The main purpose of the coil-heating burner 16 is to produce an upwardcurrent in the coils; but it also superheats the gas, so that it willnot deposit moisture after leaving the coil. The heating of the gas alsoacts to destroy its disagreeable and unhealthly qualities, the chamber1l servingto confine the heat around the coil.

It would be superfluous at this day to call attention to the deadlynature of sewer-gas to prove the value of any device by which it may berendered innoxious even if not turned to use, as in the presentinvention.

It is intended to applythis improvement to a number of contiguousvaults, all of which may be in connection, by the pipe 14. or otherwise,with a service-pipe that is in connection with a number of lamps, sothat a whole alley or street may be illuminated by this means.

I claim as my inventionl. The combination, with the vault havingreceiving-ducts and gas-discharging duct, of a cover closing the top ofthe vault, excepting the space occupied by the ducts, a coil in thegas-discharging duct, a burner beneath the coil and fed by escapinggases, and a discharge-duct communicating with said coil, allsubstantially as set forth.

2. The combination of the vault having a cover, a tank, a pipecommunicating between the vault and the tank, a coil in the pipe betweensaid vault and tank, a burner located near the coil, and a pipecommunicating be IOO tween the burner and tank, all substantially as setforth.

3. The combination, with the vault, of the tank, the heating-chamber,the gas-discharging pipe communicating between the vault and the tankand having formed in it a coil located in the heating-chagnber, a burnerlocated in the heating-chamber beneath the coil, and a pipe feeding theburner from the tank, all substantially as set forth.

4. The combination of the vault having a cover, the tank, the heatingchamber, the pipe leading from the vault through the heating-chamber andto the tank, the burner in the heating-chamber fed from the tank, andthe condensing-chamber in the pipe between the Vault and theheating-chamber, all substantially as set forth.

5. The combination, with the vault having the cover, of a tank, agas-outlet pipe communicating between the cover and the tank, theheating-chamber surrounding a portion of said gas-outlet pipe and havinga hood therein, and a burner located beneath said hood and fed from thetank, all substantially as set forth.

6. In an apparatus for the consumption of sewer-gas, the combination ofthe vault having the arched cover in the upper part thereof, thegas-tank connected by a pipe with the upper portion of said cover, thecondenser and heating-coil interposed in the pipe between the Vault andthe tank, a heatingchamber surrounding the coil and having a hoodbeneath said coil, a burner located beneath the hood, a pipe leadingfrom the tank to the burner, and an outlet-pipe for permitting thedischarge of the gas from the tank to any desired point, allsubstantially as and for the purposes herein specified.

JACOB ECKHARDT.
